Waters XSelect CSH C18 HPLC Columns

XSelect CSH C18 columns are general purpose C18 columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology enables superior peak shape and increased loading capacity for basic compounds. Packed in ultra-low dispersion hardware, 2.5 µm eXtended Performance [XP] columns enable exceptional separation performance, robustness and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption.

Waters XSelect CSH C18 Column with eConnect Column Tag

• This column comes equipped with an electronic eConnect column tag containing unique column-specific information. These NFC-enabled device-tagged columns were developed to automatically identify, track and digitally trace column use history. eConnect columns can be used on any HPLC, but its advantages are unlocked when used with the Waters Alliance iS System running Empower software.

XSelect Peptide CSH C18 Column

• Waters XSelect CSH C18 contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for peptides using either FA- or TFA-containing mobile phases. The fact that the performance of a CSH C18 column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications
• Maximum Pressure: 6000 psi (415 Bar)
• System: HPLC
